Explanation: In Isaiah 20 the LORD commands Isaiah to walk naked and barefoot for three years as a sign to Egypt and Ethiopia that they would go naked and barefoot into captivity to Assyria. This prophecy refers to Ashdod's revolt from Assyria in 713-711 B.C. "The Philistine city revolted at the instigation of King Azuri, perhaps with the expectation of Egyptian support. The Assyrian Annals charge him with refusing to pay tribute and fomenting rebellion among is neighbors. The Assyrian emperor Sargon II responded with a swift campaign that quickly suppressed any hopes for independence. He placed Azuri's younger brother, Ahimeti, on the throne, who in turn was almost immediately deposed by a usurper named Yamani. Sargon sent another expedition in 712, and Yamani fled to Egypt. An Assyrian commissioner was then appointed to manage Ashdod for the empire. ... [When Yamani arrived in Egypt,] the people there refused to harbor him or give him any further military aid. Yamani then attempted to gain help from the Nubian dynast Shabaka. This was to no avail; Shabaka was more interested in conquering the Delta kingdoms and did not want to raise Assyrian ire. Thus Yamani was delivered to the Assyrians in chains as a peace offering." (The IVP Bible Background Commentary: Old Testament, John H. Walton, Victor H. Matthews, & Mark W. Chavalas, 2000)
